    	Well, it seems we got SOME of the lag to go away, though it's still
    a little sluggish.  What I did when I upgraded from patch level 2 to 4
    was change the FUP functions to be loaded as an extension.  As a test, I
    went ahead and recompiled with the FUP installed normally (the old way),
    and lag dropped considerably.  Now, the question is, where does the
    fault sit?  Is it FUP's extension that's slowwing the process down, or is
    the extension module still in its BETA process?

    	Anyone?
